OPERATION
FIG. 20
SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the
engine shuts down. As the system shuts down, Oie low oil
light comes ON. However, once the engine has stopped
rotating, this light will go OFF, See Fig. 22 for schematic.
o Grasp the starter grip and pull slowly until you fee!
resistance. Then pull rapidly one time.
® When engine starts, move choke lever to "RUN" posi­
tion. If engine fails to start, move choke lever to "RUN"
position and puli starter rope (maximum 2 pulls).
® If engine fails to start, repeat the previous two steps.
o Once engine has started, place the Safety Latch on
spray gun to the OFF position.
o Press trigger on gun and wand assembly. Water should
spray out the nozzle.
o Adjust nozzle for correct pressure, spray angle. You
can also turn the pressure control knob to the desired
pressure setting.
o Your pressure washer is ready to use.
IMPORTANT: AN INTERNAL THERMAL RELIEF VALVE
HAS A MAXIMUM TEMPERATURE SETTING OF 140°F
(60°C). IF YOU RUN THE PUMP FOR 5 MINUTES WITH­
OUT PRESSING THE TRIGGER ON THE SPRAY GUN,
1/2 TO 1 OUNCE OF WATER IS RELEASED THROUGH
THE VALVE TO COOL THE UNIT. THE SMALL AMOUNT
OF WATER WILL DRIP OUT THE BOTTOM OF PUMP.
LOW OIL PRESSURE SHUTDOWN SYSTEM
The engine is equipped with a low oil pressure sensor that
shuts down the engine automatically when the oil pressure
drops below 6 psi. If the engine shuts down by itself and
the fuel tank has enough gasoline, check engine oil level.
INITIAL STARTUP
A delay built in the shutdown system allows oil pressure to
build during starting. The delay allows the engine to run for
about 10 seconds before sensing oil pressure.
RESTARTING
If you try to restart the engine within 5 seconds after it shuts
down, the engine may NOT start, The system needs 5 to
10 seconds to reset.
If you do restart the engine after such a shutdown and
have not corrected the low oil pressure, the engine
runs for about 10 seconds as described above and then
stops.
SIPHONING
We recommend that you DO NOT siphon your water supply
from sources other than from connecting to household
water supply.
TIPS
Initially clean an area and then check the surface for
damage. If no damage is found, you can assume it is
okay to continue cleaning. Detergents work best when
applied to dry surface.
For most effective cleaning, keep spray nozzle be­
tween 8 to 24 inches of cleaning surface.
Allow the detergent to soak in between 3-5 minutes
before washing and rinsing.
For cleaning, start at lower portion of area to be washed
and work upward, using long, even overlapping
strokes.
For rinsing, push nozzle sleeve to high pressure and
wait for detergent to clear. Start at top of area to be
rinsed, working down with same action as for cleaning.
Never use garden hose inlet to siphon detergent or
wax.
If you get the spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
If you have the spray nozzle too far away, the cleaning
will not be as effective.
Do not get closer than 6 inches when cleaning automo­
bile tires.
